It is with great satisfaction that we present the Sonus-2 plus. The first noise dosimeter of the market with measurement of the noise by frequencies in 1/1 and 1/3 of octaves

 

Why dosimetry with band filter? In view of the constant increase of labor claims for NIHL – Noise-induced hearing loss, based on medical report audiometric testest by frequencies of 250, 500, 1000, 2000, 3000, 4000, 6000 e 8000 Hz and bone pathway in 500, 1000, 2000, 3000, and 4000 Hz, the dosimeter with filter of bands will provide in addition to the traditional results, the calculation of individual Leq in all exposure ranges, avoiding possible future questions and improving worker health. The result of the frequency analysis is also essential for defining the correct hearing aid model, ensuring superior quality and credibility in your reports.
